Power Quality Improvement Using Upfc

ABSTRACT This project deals with digital simulation of 14-bus top administrator governance employ UPFC to improve the baron quality. The 14-bus system with and without UPFC atomic number 18 dumbfoundinged and simulate victimisation the blocks of MATLAB/SIMULINK. It is the most complex power electronic system for prevailling the power flow in an electrical power system. The real and reactive powers can be easily controlled in power system apply a UPFC system. The circuit model for UPFC is developed using rectifier and inverter circuits. Voltage sag mitigation using UPFC is presented. Real and Reactive power with and without UPFC are studied. 1.INTRODUCTION Flexible AC Transmission Systems (FACTS) base on power electronics offer an chance to enhance controllability, stability, and power transfer capability of AC contractable disease systems. In recent years, different FACTS controllers, which are o utlined as power electronics-based systems or other static equipments that offer control of one or more AC transmission system parameters, hand over performed a wide variety of compensating functions. In general, FACTS controllers can be classified into two distinct propagations.

The in front generation is based on the line-commutated thyristor devices with only gate energize but no gate turn-off capability. Application of this technology started with the silent Var Compensator (SVC) in the 1970s, followed by the Thyristor- Controlled Series Capacitor (TCSC). The newer generation of FACTS Controllers is based on the self-commutated voltage-sourced converters (VSC), which util! ize thyristors/transistors with gate turn-off capability, such as GTOs, MTOs, IGCTs, and IGBTs. The voltage-sourced converter (VSC) technology has been successfully applied in a number of installations world-wide of Static Synchronous Compensators (STATCOM), Back-To-Back STATCOM, Unified advocate Flow Controllers (UPFC), and transmutable Series Compensators (CSC). The family of VSC-based FACTS controllers also...If you want to get a full essay, put in it on our website: BestEssayCheap.com
